ROBERT MAW CAPON, OF LIVERPOOL, ENGLAD.

STERILIZNG APPARATUS.

Application filed August 29, 1919.

To all whom it may Concern .Be it known that l, Bonner MAW Caron, a subject of the King of Great Britain, residing in Liverpool, in the county oi Lancaster and Kingdom ot England, have invented certain new and useful improvements in Sterilizing Apparatus, oi which the following is a specification.

The present invention relates to improvements in sterilizing apparatus especially for dental purposes and it is the object of the invention to provide improved-apparatus by means of which it will be possible to sterilize dental instruments or small surgical instruments elliciently and continuously instead of intermittently in batches. The invention .further comprises various structural Jfeatures ott the apparatus all as hereafter described and explained.

The invention will be described with ref'- erence to a preferred form of construction as illustrated in the accompanying drawings in which Figure 1 is a sectional elevation,

Fig. 2 is an elevation at right angles vto Fig. 1 from the side,

Fig. 3 is a plan view, and,

Fig. 4lshows a small electrical element which may take the place of the spirit lamp 7.

in these drawings, 1 represents a cold sterilizing chamber usually of glass which is `lilled with a sterilizing fluid. On the cold chamber there is detachably arranged a metal trame comprising clips 3 and 4 in the form of downwardly depending flanges from a ring 5 and cross members 2 respectively. The ring 5 is provided with a cylindrical downwardly depending deep flange 6 -to form a cylindrical chamber which'contains a spirit lamp 7 supported within the chamber by the flange 8. The top portion of the lamp is provided with a removable annular member 9 within which the wick 10 is supported in any convenient manner.

An extinguisher 11 is arranged to clip on to the vessel 1 and a shallow cylindrical member l2 is also arranged to clip on to the vessel 1. If it is desired to reduce the flame once the water in the top sterilizing chamber, to be described hereafter, is boiled, the short cylinder 12 is placed on top of the lamp. l'n the same way the extinguisher 1l can be placed on top of the lamp when it is desired to extinguish the flame. This is shown by dotted lines in Fig. 1.,

Specification of Letters Patent.

Serial No.` 32D,68S.

The cross-bars 2 are provided with posts i3 carrying cross-bars 11i attached to a ring 15.` This ring supports the top sterilizing chamber 16 which is of much smaller diameter than the opening at its lower part and oit slightly greater diameter than the opening at its upper part. The chamber 16 is provided with a liange 19 upon which lits a reversible lid 17 which is flanged as shown in Fig. 1 and is provided with a perforated handle 18 through which the steam can escape. The top sterilizing chamber 16 con-V tains a tray 23 provided with a handle 24.

The cold sterilizing chamber 1 contains a perforated holder 20 for the reception of small instruments which holder can be clipped on to the side of the chamber as shown.

A perforated tray 21 is attached to the outside oi. the cold sterilizing chamber by clips 22 and as shown in Fig. 2 this tray has its ends cut away so that the tray will serve as a rack to support the long instruments which are laid across the two ends.

The apparatus described allows the practitioner to operate using a very improved technique since it is possible for him to sterilize his instruments continuously. The longer instruments can be dipped into the hot sterilizing chamber for a sufficient time when they can be removed and either left in the cold sterilizing chamber or removed therefrom when cold and laid across the tray 21. The dimensions of the hot sterilizing chamben the cold sterilizing chamber and the tray 21 are so chosen that instruments of standard size will be held in position so that they can be grasped by the hand and in the case of the chambers filled with liquid, the instruments will not be entirely submerged which would necessitate removing the inm struments by forceps.

In the case of the small instruments, these may be removed from the hot chamber by lifting out the tray 23 by the handle 24 or the instruments may be placed in the perforated holder 20 which if desired can be placed inside the hot chamber and then inside the cold chamber, after which if desired the small instruments therein can be emptied out into the perforated tray 21.

For heating instruments, they may be placed on top of the lid 17 or if it is desired to melt or heat frutta-perche. or the like the lid may be reversed and the vclean under side of the lid will then form the top upon Which the materials may be heated oi melted thus avoiding eontamination.

)i deolae that What I claim is v l. A dental sterilizing apparatus comprising a cold steiiliaing fluid chamber adapted to receive and hold dental instruments, a hot steiilizing i'iuid chamber and a heatei" both meunted above said @oid chamber, anda pen 4oiated helder foi small instruments adapted to he inseitedin and Viemoved from said Geld ehamhei, all ai'ianged so that nstrw ments may he continuously steiilized, Cooled and handled.

2. dental sterilizing apparatus comprising a cold sterilizing liquid `chamber, a 15 'freine fitting thereon by vClips engaging the sides of said chamhei, and a heater and a hotsteiilizing chambers carried by said fiame,all zin-ranged so that instiuments may he simultaneously steiilized, Cooled and 20 handled.
